Genes affected
SEC14L3 (HGNC:18655): (SEC14 like lipid binding 3) The protein encoded by this gene is highly similar to the protein encoded by the Saccharomyces cerevisiae SEC14 gene. The SEC14 protein is a phophatidylinositol transfer protein that is essential for biogenesis of Golgi-derived transport vesicles, and thus is required for the export of yeast secretory proteins from the Golgi complex. The specific function of this protein has not yet been determined. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2022The c.972G>T (p.M324I) alteration is located in exon 11 (coding exon 11) of the SEC14L3 gene. This alteration results from a G to T substitution at nucleotide position 972, causing the methionine (M) at amino acid position 324 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
